Abstract

Abstract: As the population and living standard of human beings rises, energy requirement also increases rapidly. In developing country like India, a major part of energy requirement is fulfilled by thermal power‐based plants. It generates pollutant gases and water vapor responsible for global warming and other environmental problems. To overcome these problems in controlled area, a continuous experimental investigation has been performed based on the hybrid solid–liquid desiccant (HSLD) containing CaCl2 (0.33 M), lithium chloride (0.66 M), titanium dioxide (0.026 M), silicon dioxide (0.316 M), copper oxide (0.067 M) for dehumidification, and CO2 removal from the atmospheric air. In addition, CO2 removal capacity of HSLD has been performed from CO2 + air mixture containing variable CO2 to air as 0.33–5.46 (wt ratio). Present study suggest relative humidity of air is reduced from 75% to ~40% at 21.5°C. Outlet air contain 36.41, 72.83, 127.45, 200.27, 291.31, 418.76 ppm, 655.45, 1238.07, 2075.57 ppm CO2 for inlet condition of 0.33 (400.66), 0.51 (619.20), 0.75 (910.60), 0.97 (1165.56), 1.18 (1420.53), 1.44 (1730.13), 1.80 (2167.22), 2.70 (3241.72), 3.85 (4625.83) g CO2 /g dry air (ppm) respectively desiccant flow rate of 6 L/min. Overall proposed HSLD could be effective for dehumidification and CO2 absorption.
